Look who's talking. You gave me an article that says Bitcoin is a currency because you forgot to read it.

What the legitimacy of Bitcoin comes down to is what accepts it as currency, which in turn prompts the question of what, exactly, currency is. If currency is considered to be government-authorized tender, then Bitcoin isn’t currency. If currency is considered to be an item that is widely accepted by legal businesses in exchange for goods or services, then Bitcoin still isn’t currency. If currency is considered to be an item that is accepted in exchange for goods or services, but doesn’t need to be widespread, then Bitcoin can indeed be classified as currency. One thing is for certain, though: The government doesn’t view Bitcoin as legal tender, and instead classifies it as a virtual currency.
